The recently released Nike 2014 “Silver Speed” Super Bowl XLVIII Air Trainer Pack has been extended, with the addition of two new styles. Joining the current three styles are the Zoom Meriwether Posite and the Sky High Premium. Both sneakers fit with the overall aesthetic of the original pack, the Zoom Meriwether Posite features a black and grey color scheme, and technically it melds the lightweight responsiveness of a trainer with the protection of a boot. While the Sky High Premium is a perfect balance of sport and style, with a concealed wedge and a full metallic leather upper.

Inspired by the golden age of football – when athletes were elevated to new heights, and the dynamic characters of the era like Bo Jackson – created a newfound excitement for the game. The Nike Knows collection also features the Bo Knows T-shirt – a tribute to the godfather of training, the Nike Futura Destroyer Jacket, Futura Tech Fleece Crew, and the Futura Snapback.

A limited release of the Lunar 180 Trainer SC is available now at Nike Sportswear; the complete Nike Knows collection will be available online and at Nike Sportswear retailers in late January.
